GRAND RAPIDS, Mich., May 24, 2007 (PRIME NEWSWIRE) -- Mercantile Bank Corporation (Nasdaq:MBWM) announced today the retirement of Gerald R. Johnson Jr. as Chairman and Chief Executive Officer of Mercantile Bank Corporation and Chairman of Mercantile Bank of Michigan. Also announced today was the appointment of Michael H. Price as Chairman, President and Chief Executive Officer of Mercantile Bank Corporation and Chairman and Chief Executive Officer of Mercantile Bank of Michigan; in addition, Robert B. Kaminski was appointed to Executive Vice President and Chief Operating Officer of Mercantile Bank Corporation and President and Chief Operating Officer of Mercantile Bank of Michigan. The changes go into effect on June 30, 2007.

After a distinguished career in the financial service industry, Mr. Johnson has decided to turn over the leadership reins to Messrs. Price and Kaminski. As the Founding Chairman and CEO of Mercantile Bank Corporation, Mr. Johnson was one of the key architects of Mercantile Bank Corporation and its affiliates.

"I have spent 35 of the past 37 years in the banking industry, and for the last 21 years I had the good fortune to serve in the capacity of Chairman and CEO of two leading banking organizations in the West Michigan market," said Gerald Johnson, Jr. "I began thinking of retiring from my full-time banking career when I turned 60 last January. Since that time Mike Price and I have discussed a succession plan, ultimately leading to my decision to step down as Chairman and CEO of the company on June 30, 2007. I have worked with Mike and Bob for more than two decades and have the utmost confidence in them, our directors and the entire Mercantile team, which is the best I have ever been associated with, to continue the tradition of exceptional performance that has gained Mercantile a national reputation for excellence since our founding almost 10 years ago."

"I have had the unique pleasure of working with Jerry for over 21 years," said Mike Price, newly appointed Chairman, President and CEO. "Jerry played a tremendous role in the formation and growth of Mercantile. All of us on the management team believe Jerry has prepared us well to carry Mercantile through the next chapters of our growth. Most of all, we wish Jerry a great retirement, good health, and the best fortune as he explores new horizons in his life." Through the leadership of Messrs. Johnson and Price, Mercantile reached over $2.0 billion in assets in less than 10 years of being open for business.

Prior to Mercantile, Mr. Johnson was appointed President and Chief Executive Officer of First Michigan Bank-Grand Rapids in 1986, and served as Chairman, President and Chief Executive Officer from 1988 to May of 1997, when he resigned to organize Mercantile Bank Corporation and Mercantile Bank of Michigan.

Michael Price has over 27 years of experience in commercial banking. He previously served as the founding President of Mercantile Bank Corporation and Mercantile Bank of Michigan since the commencement of operations in December, 1997. Robert Kaminski most recently served as Executive Vice President of Mercantile Bank Corporation and Executive Vice President and Chief Operating Officer of Mercantile Bank of Michigan. He is an original employee of Mercantile and has over 23 years of experience in commercial banking.

Mr. Johnson's retirement package will include payment to him of approximately two and one-half times his current annual base salary over an eighteen-month period, and continuation of certain of his insurance benefits for the same period. The cost to Mercantile of the retirement package, which will be expensed during the second quarter of 2007, is estimated to be approximately $1.2 million, or $0.8 million on an after-tax basis.
